Filed: 1971-08-05
Abstract: 1364541 Digital transmission; loop repeaters HONEYWELL INFORMATION SYSTEMS Inc 5 Aug 1971 [19 Nov 1970] 36949/71 Heading H4P In a bipolar signalling data transmission system where a number of stations are connected in a loop, and data is passed round the loop by each station receiving data and re-transmitting it to the next station, a repeater circuit for each station first separates the positive and negative pulses of the data signal which set and re-set a bi-stable circuit whose output is a replica of the input signal, a synchronizing signal being generated from the separated positive and negative pulses which is used to sample the output of the bi-stable circuit which samples are then transmitted to the next station. In Fig. 1 data received at terminals 26, 28 passes over an isolating circuit 24 which is shown as a transformer although may be a photoelectric isolator, to positive and negative pulse separators 30, 32 whose outputs respectively set and re-set the bi-stable circuits 34 and also via inverter 36 and OR gate 38 providing a signal which synchronises the output of a multivibrator 40 providing a synchronizing signal K. In synchronous operation of the repeater the frequency of 40 is set to be equal to the frequency of the data received but in a synchronous operation it is much higher. In the absence of a request-to-send signal RS on data terminal 22 at the station, synchronizing signals K pass over AND gate 46 and OR gate 48 to one-shot circuit 56 which supplies sampling signals to AND gates 58, 62 which receive true and inverted forms of the output of the bi-stable 34 via AND gate 52 and OR gate 54. The output of gates 58 and 62 operate a bi-polar pulse drive circuit 64 which transmits over isolator 20 the regenerated data to the next station. In the absence of received data, indicated by counter 14 not being re-set by signal J, the terminal may send data, in which case a requestto-send signal RS opens AND gate 42 to pass sychronising signals of oscillator and divider 11, 12 to one-shot circuit 56, and data to be transmitted appears on line 23 and passes through AND gate 50 to AND gates 58, 62.

Patent GB-948373-A (GB)
Title: Improvements in and relating to foamed bodies
IPC: C08J9/30
Filed: 1961-10-18
Abstract: A method of producing a sound and/or thermal insulating body of cellular gypsum comprises mixing gypsum and water with a reinforcing agent comprising polyvinyl acetate, polyvinyl chloride, resorcinol - formaldehyde resin or phenolic resin, and a foaming agent, introducing a gas into the mixture to form a cell structure therein and then shaping and drying the mixture, the mixture containing such an amount of the reinforcing agent as to allow the walls of the majority of the cells to burst to form a more open cell structure in which the individual cells communicate with each other. Material with some intercommunicating cells is prepared (for sound insulation) by using a small amount of reinforcing agent. With larger amounts closed-cell material (for thermal insulation) is obtained.  Paper, fibrous material or textile material, soaked in water or a solution of synthetic resin (to shrink it) can be applied to one or both surfaces of a foamed body or panel of the material.  A covering of fibrous material, perforated or unperforated metal or ordinary hard gypsum can also be applied.  A foamed body can also be prepared of at least two layers of different hardness, with a higher synthetic resin content (e.g. about 19% by weight) for the harder than that present in the softer (e.g. 9% by weight).  Fillers such as asbestos, glass wool or rock wool can be added to the compositions.  In an example, a composition of gypsum, melamine resin, polyvinyl acetate and a surface-tension reducing agent is mixed and air is then beaten in. The mixture is poured on to a base paper soaked in aqueous polyvinyl acetate emulsion and a further such paper is applied to the upper surface.  The panel, before the paper dries, is transferred to another mould, the lower part of which supports a number of pins for perforating the paper covering.  A covering composition of gypsum is then poured in and forced round the panel while the pins penetrate the paper.  When the gypsum has crystallized the gypsum coated panel is then heated in oven at 50-60 DEG  C. Specification 799,072 is referred to.

Title: Improved device for distributing fluid by reaction through deformable chambers for use in the braking of automobiles in particular
IPC: B60T15/04
Filed: 1928-12-20
Abstract: 302,732. Servo-Frein Dewandre, (Assignees of Gauch, A. G.). Dec. 21, 1927, [Convention date]. Fluid-pressure. - A hand or foot controlled fluid distributor particularly for controlling fluid pressure actuated brakes for vehicles comprises deformable chambers containing a fluid and arranged to react upon the controlling pedal and also upon the brakes the reaction produced being proportional to the force exerted on the brakes. As shown in Fig. 1, the distributor comprises a casing 1 carried by an arm 2 connected to the brakes and having connected thereto by a pair of brakes 3 a pedal plate 6 bearing upon a slide valve 7 which rests upon a number of sealed chambers 12 of corrugated sheet metal or other flexible material. The chambers 12 contain fluid at a predetermined pressure. The casing 1 is connected at 11 to the brake applying cylinder. Valve parts 9, 10 are connected respectively to the atmosphere and to the source of vacuum. When pressure is applied to the plate 6 the device moves bodily and the pressure is transmitted to the brakes without the intervention of the fluid pressure action until the pressure overcomes the pressure of the fluid in the chambers 12 causing the valve 7 to move in the casing and register the parts 8 and 10 thereby connecting the brake cylinder with the source of vacuum through the passage 11. If the foot and thus the plate 6 remains stationary at an intermediate position the casing 1 continues to move forward until the valve 7 assumes a lap position and the brakes are held applied. The reduction of pressure in the casing 1 is equivalent to an increase in the pressure within the chambers 12 which reacting upon the plate 6 and the foot of the operator indicates to him the pressure applied to the brakes. In a modification, a pull rod extends from the pedal &c, to a lever pivoted on the valve casing and controlling a valve rod and a second pull rod extends from the casing to the brakes. The valve rod carries a transverse arm arranged to actuate a pair of lift valves controlling the atmosphere and vacuum connections respectively.

Title: Improvements in deposition of pyrolytic graphite
IPC: C04B35/52
Filed: 1967-08-18
Abstract: 1,206,118. Moulding tubes. GENERAL ELECTRIC CO. 18 Aug., 1967 [3 Oct., 1966], No. 38101/67. Heading B5A. [Also in Divisions C1, C7 and F2] An article, e.g. a tube of anisotropic pyrolytic material is made by depositing material on to a shaped surface which provides a fault extending through the deposit, a cylindrical portion on one side of the fault, and a portion having a surface of double curvature on the other side of the fault. The portions on either side of the fault are under sufficiently different stress from each other to enable cleavage at the fault upon cracking. The deposition of pyrolytic graphite is particularly described, but metals, e.g. Hf, Mo, Nb, Si, Ta, W, Ti, Zr, and their nitrides, silicides, carbides and borides can also be deposited. Graphite can be deposited from methane/hydrogen by induction heating at 1200-2500‹ C., metals from halogenated derivatives, and nitrides or carbides from said derivatives plus ammonia or carbonaceous gas. As shown in Fig. 3, deposition takes place upon the inside of a tubular mandrel 30 of frangible electrographite, provided at each end with shoulder 36 and portion 38, which are assembled by means of flanges 32, 34. Portions 30, 38 are of simple curvature and shoulder 36 is of double curvature. The deposit contains faults 54, 56, 58, 60 and is stressed in tension on shoulder 36 and in compression on mandrel 30 and portion 38, so that a cleavage takes place at the fault lines, whereby the desired tubular deposit on mandrel 30 is separated from the impure end portion 38. The flanges may extend at 30-150 degrees from the mandrel surface, and flange 34 may be omitted. As shown in Fig. 4, tubular deposits 68 and 70 are separated by a deposit which is under tension, on shoulder 62 of double curvature; cleavage takes place at faults 72, 74.

Title: Manual dispenser for the dispensing and affixing of adhesive  labels
IPC: B65H37/00
Filed: 1971-08-13
Abstract: 1330120 Manual label applicator HEINRICH HERMANN 13 Aug 1971 [7 April 1971] 38203/71 Heading B8F A manual label applicator for adhesive labels with one- or two-sided coating on a backing tape comprises a bearing 3 for the label tape reel and an affixing roller 5 driving a feed roller 4 and a tensioning roller 6 with circumferential velocities less than its own, that of roller 6 possibly being greater than that of roller 4. A gear-wheel on roller 5 drives a ring gear which drives a gearwheel on roller 4 which meshes with that on roller 6. The label tape is held against rollers 4, 6 by leaf springs 8, 7 respectively, the spring 8 being removable as it is not required for labels coated on both sides. The springs can be disengaged from their respective rollers to facilitate changing tapes by means of spigots on a lever 10 which can be pushed inwardly for this purpose. When the upper case cover is fitted, a projection on it holds lever 10 in its inoperative position by bearing outwardly against handle 10e. The rollers are fitted with silicone rubber rings to prevent adhesion of labels to them. Labels are removed from the backing at deflecting edge 9 and applied to the surface by roller 5 on which the device is pulled across the surface. As a label comes away from the backing the tension in the tape due to the greater circumferential velocity of roller 5 is released causing a jerk which indicates the detachment of a label.

Title: Improvements in or relating to lawn mowers
IPC: A01D34/62
Filed: 1930-12-19
Abstract: 369,567. Lawn-mowers. BEESTON, W. W., Crescent Works, Horseshoe Crescent, Beaconsfield, Buckinghamshire. Dec. 19, 1930, No. 38375. [Class 6 (ii).] In lawn-mowers of the kind wherein relative adjustment of a cutting cylinder 10 and a stationary blade 23 is made by moving each end of the cylinder or blade in straight guides under control of a screw 18 and a spring 20, the screws 18 are actuated by a common transverse shaft 32 arranged to give equal adjusting movement to each end of the cylinder or blade. The cylinder 10 is mounted on a shaft 11 carried in ball bearings 12. When adjustable, the bearings 12 are housed in blocks 13 which slide vertically in slots 14 in side plates 15. Grooves in the blocks 13 engage the edges of the slots 14. The actuating screw 18 is mounted on a collar 22 of a gear casing 21 and is received in an internally threaded collar 17 of the block 13. The spring 20 is seated between a collar 19 on the block 13 and the casing 21. The screw 18 is driven by a worm wheel 24, worm 31 and a squared shaft 32 mounted in a casing 33 and rotated by a crank handle 36. A squared portion 27 of the screw 18 is engaged by a washer 26 carrying a pin 29. Connection between the screw 18 and the wheel 24 is made by the pin 29 detachably engaging the wheel 24. When an obstruction is encountered the block 13, screw 18, and pin 29 rise against the action of the spring 20 and the drive is disconnected. In order to bring the cylinder 10 and blade 23 into alignment the shaft 32 may be moved axially out of engagement with the worm 31 remote from the handle 36 and replaced when the adjustment has been made. In constructions where the blade is movable, the screw 18 engages a collar having depending arms carrying a plate whereon the blade 23 is mounted, movement being controlled by springs on the arms. Provision is then made for moving the blade and cylinder apart on meeting an obstruction by removing the head 28 and placing a collar on the screw 18 and bearing against and underneath the collar 22, the springs on the depending arms being then mounted so as to force the plate upwardly. The casing 33 is held between lower and upper portions of the gear casing 21 and thus serves as a transverse stay.
